# Image Hash

This section describes the actions that you can use to train image hash analysis.

NOTE: Apart from ListImageHashDatabases, ListImageHashes, and GetImageHashImage, all of these actions are administrative actions. Administrative actions can be sent only by users who belong to an authorization role that allows the `Admin` standard role, or which enables the action explicitly. See Authorization Roles Configuration Parameters.
